    摘要： This invention describes a new refrigerant/lubricant combination for use in stationary and mobile refrigeration and air conditioning applications. In these applications, the refrigerant and lubricant must be soluble in each other (e.g., miscible) to ensure adequate lubricant circulation from the compressor, through the condenser, expansion device, and evaporator, and back to the compressor. Insufficient lubricant circulation will result in compressor failure. Low temperature solubility is particularly important to ensure lubricant flow through the cold evaporator. In addition, the lubricant and refrigerant combination should be stable in the presence of steel, and aluminum and copper containing metals. This invention describes the combination of refrigerant difluoroethane (e.g. R-152a) and polar, oxygenated lubricants, particular polyalkylene glycols (PAGs) and polyolesters (POEs) which may be used as a replacement for R-134a.

    摘要翻译： 本发明描述了一种用于固定和移动制冷和空调应用的新的制冷剂/润滑剂组合。 在这些应用中，制冷剂和润滑剂必须彼此溶解（例如，可混溶），以确保从压缩机，冷凝器，膨胀装置和蒸发器的充分的润滑剂循环，并返回到压缩机。 润滑剂循环不足会导致压缩机故障。 低温溶解度对于确保润滑剂流经冷蒸发器是特别重要的。 此外，润滑剂和制冷剂组合应在钢铁，铝和含铜金属的存在下稳定。 本发明描述了可用作R-134a的替代物的制冷剂二氟乙烷（例如R-152a）和极性，含氧润滑剂，特定聚亚烷基二醇（PAG）和多元醇酯（POE）的组合。

    摘要： A high viscosity synthetic ester base stock of about ISO 68 to 400 is formed from a neopentylpolyol condensed with at least one monocarboxylic acid selected from the group consisting of linear acids having between 4 to 10 carbon atoms and branched chain acids having from 5 to 10 carbon atoms in an excess of hydroxyl to carboxylic acid groups to form a partial polyneopentylpolyol ester that is further reacted with the same or similar acid to form a high viscosity polyneopentylpolyol ester. Lubricants formed from the base stocks have satisfactory miscibility with standard highly or fully fluorinated refrigeration fluids.
